Helical gears operate using angled teeth cut along the gear’s circumference, allowing for smoother and quieter engagement compared to straight-cut (spur) gears. Here’s how they work: • Angled Teeth: The teeth are set at an angle to the gear’s axis, forming a helical shape. This design allows the teeth to engage gradually, which significantly reduces noise and vibration. • Continuous Contact: Unlike spur gears, where teeth meet all at once, helical gears have multiple teeth in contact at any give
